Without the reducer, I get MINIMAL vignette on the full frame 5DMkII sensor. With the FR, the vignette is severe - at least a quarter or so of the image underexposed. That was using an FR made for Vixen's ED series of refractors, so hopefully, the vignette will NOT be as pronounced with the correct made-for FR, and the smaller chip size

I just hope I have my maths right re focal plane to reducer distance - I'll be asking a separate question about that
